Possible, but no confirmation on that unfortunately. It'd kind of be neat since there's no real imagery to show what he's sporting under the robes, or are there pics of Sidious somewhere and that he's just sporting Sithy Robes like the figure ultimately was done originally?

I don't know if he was in the display case, so I guess the slideshow is the best pic we have so far... it doesn't show much. Someone with a keener eye than me can take a look to see what they spy under the hood/robes:

I checked the updated photos that Galactic Hunter ran, but the only TPM figures shown appear to be Quinlan Vos, the Naboo Royal Guard, post Senate Amidala, Padawan Anakin and Ben Quadinaros.
